Table 1 Identified nuclides with their lifetimes, their excited daughters and their \(\upgamma\)-ray energies from literature18, 19 as well as the number of collected nuclides per shot in the filter and the calculated integral cross-sections.
From: First on-line detection of radioactive fission isotopes produced by laser-accelerated protons
